EXECUTIVE SUMMARY
Energy plays a key role in the economic growth of the country. There is a close link between the Energy & future growth of a nation. Not only in India but in the entire world there is a never ending need for energy. Since, times immemorial, the energy are derived from one source or another. In much older periods, the demand for light & fuel was met with traditional sources like wood or animal dung or waste plants. Later they got replaced by coal, water & nuclear energy which were then available in abundance. But as the time goes on, the limitations & drawbacks are stepping forward making the hunt for alternative sources of energy a must, considering the future generation & their needs. More awareness is generating for using the environment friendly resources. Though sunlight is considered a “compelling solution” to the “need for clean, abundant sources of energy,” solar energy currently provides only 0.01 percent of the total electricity supply needs. However, recent market trends, regulatory pressures, consumer incentives, and technological advancements are together driving solar energy costs drastically down relative to conventional fossil fuel-derived energy. Compared to conventional and other renewable energy sources, solar power is especially attractive because it can be easily scaled up Solar electricity can also be generated nearer to consumers and even on site, which greatly reduces or eliminates transmission costs and losses. Furthermore, the increasing adoption of variable-pricing or net metering schemes also favors solar electricity. Under these schemes electricity rates are higher when peak demand is highest and this generally correlates to when more solar energy is available and electric output highest. Solar costs are also presently being lowered through higher volume production, improved manufacturing techniques, and alternative solar technologies that reduce the amount of semiconductor material. Total installed system costs are further being reduced through cheaper “balance-of-system” components such as inverters through improved design and installation techniques. Fundamentally, the solar industry as a whole has advanced and grown to the point where solar solutions are not only an environmentally friendly option but also a cost effective one. The Ministry of Power has a mandate to promote cogeneration and renewable sources for Power generation under Nodal agencies and hence it will play a major role in mainstreaming renewable energy sector.
Assuring you about our robust project design, reliability and best support, Lanco Solar Energy Private Limited has got an opportunity to closely work with you to implement this 20 kWp SPV power Plant. This Detailed Project report brings out the technical details & overall cost mitigating this project. The total power to be produced by the solar cells will be 20 kWp. The cell technology proposed here is of crystalline type.

9. SOLAR PV POWER PLANT DETAILS 9.1 SOLAR PV MODULE: A solar panel (photovoltaic module or photovoltaic panel) is a packaged interconnected assembly of solar cells, also known as photovoltaic cells. The solar panel can be used as a component of a larger photovoltaic system to generate and supply electricity in commercial and residential applications. Because a single solar panel can only produce a limited amount of power, an installation will contain several panels. This is known as a photovoltaic array. A photovoltaic installation typically includes an array of solar panels, an inverter and interconnection wiring. Solar panels use light energy (photons) from the sun to generate electricity through the photovoltaic effect. The Wattage of SPV Modules for the proposed system will be as per system capacity. The type of SPV Modules provided will be of crystalline Silicon type with efficiency of about ≥14 %. The solar module will be made up of transmissivity glass front surface giving high encapsulation gain, employing lamination technology using established polymer (EVA) and Tedlar or Polyester back sheet and hot butyl rubber edge sealant for module protection and mechanical support.

Suitable number of Array frames will be provided. The array frames proposed for the site would typically utilize design with a different tilt angle capability. This is typically achieved by changing the length of the rear support leg and the spacing between the front and rear footings. The array frames are made of MS galvanized/Aluminum and is protected against the salt mist corrosion and other environment impacts. The array frames will be corrosion resistant. The array frames would be certified for wind and seismic requirements of the area and most importantly, for a remote site, would utilize footings that will minimize the quantity of concrete required. The array frames are designed for simplicity, low cost and ease of installation at site. The structure can be installed with a fixed inclination by selecting required angle slots available. The design will be such that any module can be replaced easily. The galvanized steel structure provides support for the photovoltaic modules and has longer life and gives them the optimum angle of inclination, dependent on the system location .The Structure consists of a set of components that can be managed and mounted in the place where the installation is going to be realized. These structures are designed to survive adverse weather conditions with minimum maintenance. The structure will be supplied with all members to be compatible allowing easy installation at the roof‐top site. The details are as under‐ Attributes

9.3 INVERTER Solar photovoltaic is DC (Direct current) source. The DC output has to be inverterd to the grid alternating current (AC) by a power electronic device referred to as inverter/power conditioning unit. The synchronization happens automatically with available grid voltage & frequency and it starts to feed module output into grid. The second important job of the solar power inverter is to operate the PV system at its maximum power point (MPP) & extract maximum generation. The MPP is defined as the operating point where combined value of voltage & current result in maximum power output. This MPP fluctuates during operation in an interval depending upon the radiation, cell temperature & the cell type and it has to be tracked by the inverter controller unit. The Inverter for the 20 kWp SPV power plant will be a grid connect which will be a combined unit comprising of inverter and necessary protections. Merits of a Grid Connected inverter are;
Easy to install High efficiency Reliable operation
Robust against grid fluctuation
